Aiden watched as his sister stepped outside for some fresh air, leaving him alone with her BFF, Maddie. He couldn't help but feel aroused by the thought of being alone with her. He excused himself to get a massage oil, returning to find Maddie already undressing, her perfect ass glistening under the dim light. They exchanged heated glances as Aiden began massaging her muscular thighs, then moving up to her firm breasts. His erection throbbed against his pants as he slowly rubbed her clit through her wet pussy lips. "I've always wanted to do this," he whispered, slipping a finger inside her hot tunnel. Maddie moaned, arching her back in pleasure. Aiden's cock twitched, begging to be freed. In one swift move, he pulled down her panties and pounced on her quivering body.
